I can't seem to get master slave working in 4.1 -- I configured the
master and slave according to the instructions on the site. They
start up OK, and I can see from the logs that the slave attaches to
the master. But, as soon as the first connection is made to the
master, the slave dies. The master log looks like:

exclusive lock to become the Master broker

dataSource: [EMAIL PROTECTED]
